Send SQL queries to Sentry by using our own port of pg_query

What does this MR do?

The previous attempt to address #235161 (closed) with !45724 (merged) has failed because of a compilation problem of the pg_query gem on ARM platform. The patch to fix pg_query has already been prepared by @stanhu but we decided to use our own fixed version of the pg_query until the fix has been merged into upstream/master.
